Problems solved by technology

[0002] As the requirements for distribution network automation become higher and higher, automatic switch installation is being carried out on a large scale. In the process of automatic switch installation, there are many important links that need to be regulated: first, the safety distance from the upper operating line, safety supervision It has been found many times that the safety distance is insufficient to carry out construction. This is a serious type of violation, and personal electric shock accidents are extremely likely to occur; The impact of electric poles is very easy to damage the equipment, and the work efficiency is low and unsafe; the third is that the spreader used does not match the insulation device, which has no protective effect and low work efficiency

Embodiment Construction

[0012] A special device for hoisting the distribution network automatic switch with an insulating cover, including an insulating baffle 1 that is hoisted between the distribution line or equipment for maintenance and equipment without insulation shielding or safety shielding measures, and the insulating baffle is divided into two pieces, left and right , the left and right two pieces adopt hoop 2 to fix.

[0013] The hoisting method adopts triangular hoisting.

[0014] When making, first determine the size of the insulation guard:

[0015] 1. According to the requirements of safety regulations: those who need to cut off the 10kV power to work are: those who have to cut off the power of 10kV lines and equipment or take safety measures (Article 3.3.2 and Article 4.2.1 of "Power Distribution Safety Regulations"): 1. Overhaul distribution lines or equipment. 2. Operating lines or equipment adjacent to maintenance distribution lines and equipment with a safety distance of less th...

Abstract

The invention discloses a special device used for distribution network automatic switch hoisting and provided with an insulating cover. The device comprises an insulating baffle plate hoisted between an overhauled distribution line or equipment and equipment without insulating shielding or safety shielding measures, the insulating baffle plate is divided into a left block and a right block, and the left block and the right block are fixed by a shroud ring. The special device is fast to install, and time consumed by of a traditional mode is long; the combination of lifting and insulation is realized, and the space is saved; and installation materials are saved.

Description

technical field [0001] The invention relates to a special lifting device for an automatic switch of a distribution network. Background technique [0002] As the requirements for distribution network automation become higher and higher, automatic switch installation is being carried out on a large scale. In the process of automatic switch installation, there are many important links that need to be regulated: first, the safety distance from the upper operating line, safety supervision It has been found many times that the safety distance is insufficient to carry out construction. This is a serious type of violation, and personal electric shock accidents are extremely likely to occur; The phenomenon of electric pole impact is very easy to damage the equipment, and the work efficiency is low and unsafe; the third is that the used spreader does not match the insulation device, which has no protective effect and low work efficiency. [0003] In this context, the development of d...
